CrossFit Coach

CrossFit isn’t just a fitness craze — it’s here to stay. Developed in 2000 by Greg Glassman, a former gymnast and personal trainer, CrossFit creates individual workout regimens full of constantly varied, functional, high-intensity movements.

It also has attracted deep loyalty from customers by promoting a strong sense of community throughout its more than 13,000 global affiliates. Specialized coaches are always needed to teach at those gyms.
